I see more peoples take on the board(s) were created. Because I had sooo many problems with this pedal, I just walked away from it for a long while. I may get back into it to figure out wtf was the problem now that the Summer is over and I have some time. I wonder if just upping the one cap as outlined pages ago would help?

I see there is the latest board that states no oscillation but looks like a hybrid as through-hole and SMD! I'm wondering why SMD at all and if you're going to do that, why not just create and EXACT clone, depopulate the pedal, and make a PCB from it and just post it. Then people would purchase the exact components and eliminate all of the osciallation and issues we had??

In regard to the top comment and link....it seems Friedman adds the MIDDLE pot to the Buxom and Shirley. I know Friedman's design are bascially exactly the same with small tweaks and the Middle pot was not included as a single pedal package was already maximized with 6 post, but think seeing how done in these other pedals and incorporating into the BE-100 with a larger enclosure would be a huge win!

My thoughts.

Upping the cap may reduce or eliminate the oscillation, but it will affect the tonal response of the pedal. Using short and shielded wires, especially on the input and the pots may help.

The layout uses smd IC because I have a lot of them, and SOIC-8 and SOT-23 are pretty easy to solder (i don't even turn on the hot air station for these packages). I confirm that the layout is free of oscillation even with the gain control and gain trimmer maxed

Here's the layout. The reason that I didn't show my layout is there's many unpredictable cases.

I've been working on layouts to take into account the size of the parts, but in reality, there will be many challenges.It is important to choose the size of the parts. I will give you some notes.

1. The film capacitors must have a lead spacing of 5mm.2. The capacitors in pF should be chosen to be able to be mounted at 2.5mm intervals. (ceramic or monolithic would be good)3. Electrolytic capacitors height must be 7mm or less.4. If use the 8 pin / 14 pin exclusive IC socket, you can't install resistors under the IC socket. So you must always cut out four or seven slots in a row and use them in two rows.5. Wiring must be connected on the soldering side, not on the parts side.6. Potentiometers must use 9mm size.7. To secure the height to which the PCB is inserted and to insulate it, use a box jack as shown below and install as close as possible to the top of the case

Drilling guides are slightly different in size from case to case, so you will have to arrange them yourself by yourself.

It is not easy to make it, and it is difficult to make it more reliable than anything else.You should be careful not to have shorts or disconnection.

Good luck to you.

There is a little noise, but it's because of the amount of distortion.The noise does not make you feel uncomfortable.I know that the original pedal also has a lot of noise.Perhaps if you use not such a complicated layout, it will have less noise. If so, no one will feel the image that this pedal is noisy.

Used 470pF instead of 120pF, and looks like I forgot to order the 10k rev Log pot for Presence, so I used 10k linear and it's still usable Also, used 1N4148's as seen on photos, and TL082's instead of TL072, only had one TL072.The protection diode is 1N4001 probably, I didn't have the other one that's noted in the original schem, it's just reverse polarity protection, it doesn't matter.

Only tried it with a small crappy solid state amp, but it sounds great, even through that I like how the treble and presence react to each other, and overall all the pots are quite useful, especially the "Tight" knob.No oscillation, even with the trimpot fully clockwise, tight build for 1/4 resistors!

I've been busy with amps, but finished up yesterday, so will circle back around into seeing why all of the BE-OD clone (2-vero, 2-pcb) do not work!! People seems to be getting both variations done and the one common theme is "me", so I need to see what the fuck is up. I've built hundreds of pedals and never had problem(s) like this and nothing works. Components are correct and orientation and no apparent solder bridges. I'll try connecting the pots directly on and increasing the cap as many have suggested. Other than that, I'm out of options. It should work, but doesn't and some pots in reverse direction!

Hi rmroza, I'm just wondering if you managed to get to the bottom of the problem you had with the 4 different builds you made of this pedal. It would be helpful to us all if you got it sorted.

It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?
